especially in a double action revolver.The 356 GNR in a 5" barrel will do almost 1800 FPS. Your best bet would be to simply rechamber your 357 mag cylinder to 356 GNR. Otherwise you would have to take the whole gun apart every time you change calibers, as the new cylinder would have a new crane and the whole cylinder assembly with it. Plus due to the extreme velocity gain you would have to re-sight your GP in every time you change calibers.
